Prefilter
The prefilter is located just below the HEPA filter. Its
purpose is to lengthen the operating life of the HEPA
filter by removing large particles before they can block
it.
REGULARLY SCHEDULED
INSPECTION AND REPLACEMENT
)
OF THE PREFILTER IS KEY TO
MAINTAINING PROPER
OPERATION OF THE ENCLOSURE.
HEPA Filter
HEPA filters are disposable, dry-type particulate filters.
The filter material or media is typically made of
borosilicate microfibers that are made into a thin sheet,
in a process similar to the production of paper. This
sheet is folded, or pleated to increase its surface area.
The pleats are held in place by aluminum diffusers or
by beads of glue that add rigidity to the media pack.
The media pack is then set into a suitable frame, and the
perimeter sealed to the filter frame, as shown in Figure
4-1.
The HEPA filter media is very fragile.
!
Do not touch or contact the media
surface. If you think the surface of a
HEPA filter is damaged, DO NOT
USE THE STATION. Have the
HEPA filter integrity tested by a
qualified certifier before using the
station.
HEPA Filters are only effective
against particulate material. Gases
will pass through the filter.

The Activated
Carbon/Alumina Postfilter
The postfilter in your Bedding Disposal Station is
unique. Inside of its polyester media are granular
activated carbon for the adsorption of odors, plus
activated alumina impregnated with potassium
permanganate, for additional removal of odors and light
gases.

Chapter 4: Theory Of Operation And Safety Precautions
Directional Airflow
Directional airflow also plays a key role in the Bedding
Disposal Station’s performance. Air is drawn into the
front of the station and odors. This “curtain” of air
makes it difficult for aerosols and odors to escape out of
the work area and into the outside environment. This
airflow is often calculated and referred to as the
Average Inflow Velocity. This is shown graphically in
Figure 4-2.

Impellers
The impellers pull air into the front of the station,
through the pre- and HEPA filters, and then discharge it
through the postfilter.
Speed Control
The speed control should only be

The speed control is an electronic circuit that allows the
certifier to set the impellers’ speed by adjusting its

HEPA Filter Leak Test
Procedure
To ensure dirty room air does not affect the HEPA
Filter Leak Test and that the control panel and sash
gaskets are sealing, take the following steps:
1. Turn on the enclosure and set the average inflow
velocity as indicated in inflow velocity test
procedure. Remove the postfilter
2. Tape closed all openings full length across top,
front and sides of the front dress panel as shown
in Figure 6-7.
3. Turn the photometer on and calibrate it per the
manufacturer’s instructions. The upstream
concentration of DOP will be approximately
24 ug/l. Use these values to establish the
upstream value of 100%.
Product Service 1-800-522-7658
35
Chapter 6: Maintaining Your PuriCare
4. Place photometer pickup over the exhaust
discharge and sample the concentration. The
concentration must not exceed 0.005%.
5. If the unit fails, check the gasket between the
control panel and the upper cabinet flange.
Also, check gasket attached to underside of the
upper cabinet for contact with the upper edge of
the sash when it is in the closed position.
6. Use a Laskin nozzle-type generator. DO NOT
use more than one nozzle. Operate the
generator at 10 PSIG. The calculations listed
above are based on the use of Di-octyl-Pthalate
as an aerosol challenge. You may need to
correct the valves listed if you use an alternate
fluid.
7. Place the generator discharge near the work
access opening of the enclosure.
8. Start the generator. Ensure that only one nozzle
is operating at 10 PSIG.
9. To establish the downstream concentration of
aerosol, place the photometer pick up over the
exhaust discharge, and sample the concentration
at several locations.
10. The average concentration at each of the points
must not exceed 0.005% of the upstream
concentration.

Inflow Velocity Test Procedure
Inflow velocity can be determined by use of a thermal
anemometer at the face of the work access opening by
taking the following steps:
1. If the meter has an adjustable time constant, set
it at 10 to 15 seconds.
2. Take three rows of readings at 8, 12 and 16
inches from the top of the opening at positions
that are 6 and then 12 inches in from both
sidewalls. This will yield a grid of 12 sampling
points. See Figure 6-8 for probe placement.
3. Add the 12 readings together and divide by
twelve to obtain the average inflow velocity.
4. The factory inflow velocity setting should equal
or exceed 65 FPM. The blower speed can be
adjusted by turning the speed control located
behind the front dress panel.

Chapter 6: Maintaining Your PuriCare
Airflow Smoke Patterns
Non-thermal smoke should be released from one side of
the enclosure to the other, along a line in the middle of
the work area, two inches above the work surface. The
smoke should flow directly into the rear baffle. Smoke
released near the front end of the enclosure, or at the
top of the enclosure may exhibit vortexing and a reflux
along the sidewalls or top of the enclosure. This
turbulence is normal and does not negatively impact
containment of aerosols above the disposal hole.
Motorized Impeller
Replacement
The motorized impeller should be replaced by a
qualified certifier. The motorized impeller is a nonserviceable component and must be replaced as a unit.
When the motorized impeller is replaced, its capacitor
should be replaced with a new one. Following
replacement of the motorized impeller, the cabinet
MUST be recertified by a qualified certifier.
1. Unplug the enclosure. Remove the post filter.
Remove the top panel by removing all of the
fasteners on the top as described in the
Customer Service Operations section of this
manual.
2. Disconnect the motor ground wire from the
frame. Disconnect the wires connecting the
motorized impeller to the wiring harness.
3. Using a small wrench, remove the four lock nuts
that secure the motor brace to the blower shelf.
Remove the brace and motorized impeller as an
assembly. Placing the assembly on a flat
surface, remove the four screws that secure the
motorized impeller to the brace. Disconnect the
two wires from the motor to its capacitor,
located on the side of the brace. Remove the
motorized impeller from the brace.

Product Service 1-800-522-7658
Chapter 6: Maintaining Your PuriCare
4. Replace the capacitor with a new one of equal
voltage and capacity.
5. Reassemble the unit by reversing the
disassembly steps. Recertify the enclosure.
Storage
If the Bedding Disposal Station is to be left unused for
more than one month, the unit should be prepared for
storage.
1. Surface disinfect or contaminate the cabinet as
required.
2. Unplug the unit.
3. Cover and seal the work area access opening
and the exhaust outlet with plastic sheeting.
4. Ensure that the cabinet will not be moved or
disturbed while in storage.
The cabinet should not be stored in excessive humidity
or temperature extremes. If the cabinet is moved during
storage it must be recertified before use.
